ELECTRICAL Application filed June 5,

This invention relates to electrical condensers, and more particularly to fixed electrical condensers, or condensers of constant capacity in a vacuum.

An object of this invention is the production of a condenser in vacuum or rare gas, possessing high efiiciency in operation, yet markedsimplicity as a whole and in respect to each of its component parts, so that its manufacture is economically facilitated as'to both the parts and their assembly.

With these and other objects in view which may be incident to my improvements, the invention .consists in the parts and combinations to be hereinafter set forth andrecited in the claims, with the understanding that the several necessary elements comprising my invention, may be varied in construction, proportions and arrangement without departing from the spirit and scope of the invention.

In order to make my invention more clearly understood, I have shown in the accompanymg drawings means for carrying the same into practical efl'ect, without limiting the improvements in practice tothe particular constructions, which for the purpose of explanation, have been made the subject of illustration.

In the drawings forming a part ofthis v specification:

Figure 1 is a view in side elevation, the casing being shown in section;

Fig. 2 is a vertical sectional view taken on line 22 of Fig. 1;

Fig. 3 is a cross sectional View taken on line 3-3 of Fig. 2;

Fig. 4 is a top plan partly broken away. Referringby numerals to the drawings, 1 represents ,a casing which is preferably rectangular in general contour. In the-top of the casing is a circular opening 2 formed with a flange 3. A cylindrical glass sleeve 4 is mounted upon the flange 3 by means of a slot 5 in the lower end of the sleeve in which the flange 3 is cemented or sealed in any deview, the casing being sired manner. The sleeve 4 is formed upon its upper edge with a slot 6 in which is mounted and sealed ahead or cap 7 having a cenn. Y., A CORPORATION or DELAWARE oonnnnsnn 1925. Serial at. 35,259.

tral aperture 8, the object of which will hereinafter appear.

- Mounted within the casing 1 is a condenser comprising electrically conductive elements or plates 9 and 10 of opposite polarity arranged alternately within a frame. The frame comprises two metallic I-shaped end plates or members 11 and 12 secured together by rods or bolts 13 at the end of each vertical arm of the I plates, and oppositely disposed rods or bolts 14 centrally located between the In normal position bolts 13 in said arms. the plates 11 and 12 are vertical, and all the bolts horizontal.

Transverse horizontal glass, mica or other non-conducting bars or members '15 are mounted u on the bolts 13, and bear against the inner aces of the I plates 11 and 12 at the upper and lower ends of the arms, thus connecting the ends of the arms of the I plates. upon the bolts 13*and 14 with alternating insulating washers .or spacers 16. The plates 9 are fitted snugly on the rods or bolts 13 and 1/1 to insure perfect contact, and the spacers 16 are of sulficient thickness to admit of interleaving the condenser plates 9 with the condenser plates 10 with suflicient clearance to produce the bestresults. I

The glass, mica or other non-conducting bars 15 mounted upon the rods or bolts 13, are centrally bored.to receive rods or bolts 17 which are retained therein by washers or nuts 18 fitted over their respective ends. The bolts 17 of course do not make contact with. the casing 1. The condenser plates 10 are mounted upon the bolts 17 alternately with insulating washers or spacers 19. The. plates 10, which interleave the plates 9, are fitted snugly on the bolts 17 to insure perfect contact and are connected by an insulated terminal 20. The terminal 20 projects through the opening 3 and an aperture 8 in the hood 7, and is sealed therein, as shown at 21. An.

outside conductor can be joined to the extremity 22 ofrthe terminal 20.

Air is evacuated from the casing through the sleeve 4, or the casing may be filled with rare gas, or the air may or may not be evacu- NEW YORK, ASSIGNOR TO DUBILIER .OON-

The condenser plates 9 are mounted ated, either being within the scope of my invention.

The plates 9 thus extend from side to side in the casing 1, and the plates 10 are Vertical between the plates 9, and their opposite lateral edges lie between the upper and lower bolts 13, and between the two bolts 14.

The conductor 20 is connected to the upper bolt 17, which has a snug .fit in the apertures through all the plates .10, and thus electrically unites these plates. Also the bolts 13 and 14 similarly unite the plates 9, and the ends of the bolts 13 and 14 and of the members 11 and 12 make contact with the inner surface of the casing 1. Hence the plates 9 The unit made up of the members 11 and t 12, plates 9 and 10, bars 15, bolts or parts 13, 14 and 17 with washers 16 and 19 may fit the casing 1 snugly, and either rest on the bottom of the casing, or on supports 24 therein, if desired.

The casing can be made in one piece or several pieces united by sealed leak-proof joints, and after the condenser is disposed in the casing, the air can be pumped out through the neck or sleeve 4, and the latter then sealed in the well known way. The casing can be set up with the terminal 20 vertical as shown, or in other positions.

While I have shown and described the preferred embodiment of my invention, I

wish it to be understood that I do not confine myself to the precise details of construction herein set forth, by way of lllustratlon, as it is apparent that many changes and variations may be made therein, by those skilled i.n'the-..-art', without departing from the splrit frame and in contact therewith, electrically upon the other rods connecting the end members, and spacers between said elements.
